Marleybone Station
Fenchurch St Station (been past it loads, never had a reason to go in
Marlborough St
Vine St (I can find two Vine Streets in London, one in the West End, one near Aldgate, both small and inconsequential. Why was it chosen? In any case, I haven't been to either of them).

It's The Angel, Islington. THE ANGEL ISLINGTON. It's the same thing. Plus I've used Angel Tube and taken cash from the bank that now stands on the site of the original. I've been to that place. I've been there.

'In the 1930s, John Waddington Ltd. (Waddingtons) was a firm of printers from Leeds that had begun to branch out into packaging and the production of playing cards. Waddingtons had sent the card game Lexicon to Parker Brothers hoping to interest them in publishing the game in the United States. In a similar fashion, Parker Brothers sent over a copy of Monopoly to Waddingtons early in 1935 before the game had been put into production in the United States.
The managing director of Waddingtons, Victor Watson, gave the game to his son Norman (who was head of the card games division) to test over the weekend. Norman was impressed by the game and persuaded his father to call Parker Brothers on Monday morning – transatlantic calls then being almost unheard of. This call resulted in Waddingtons obtaining a license to produce and market the game outside of the United States. Watson felt that for the game to be a success in the United Kingdom, the American locations would have to be replaced, so Victor and his secretary, Marjory Phillips, went to London to scout out locations. The Angel, Islington is not a street in London but an area of North London named after a coaching inn that stood on the Great North Road. By the 1930s, the inn had become a Lyons Corner House (it is now a Co-operative Bank). Some accounts say that Marjory and Victor met at the Angel to discuss the selection and celebrated the fact by including it on the Monopoly board.'

there are a few monopoly books and i can't find the one i mean. this was more like the history of it and the maths behind it and a bit about the author playing it as a kid. that's what i remember from it anyway

Used to have a police station which was known as the busiest police station in the world in the early 20th century . I don't know if this has any bearing on it being picked to be on the monopoly board.
